He stood in the middle of the stone floor, matchbox in hand, trying to decide what he must do next. As nearly as he could judge by his observations during the afternoon, and the direction of the steps and passageways, the vault was somewhere under the main group of buildings, the keep or one end of the Hall, two or three stories below the level of the chapel floor. Part of the corridor through which he had passed was hewn from the solid rock, and part was built of masonry. The wooden partition opposite him was obviously the beginning of the used part of the castle, but admitting that he could pass it, in which direction would it lead him? He feared to strike another match, for beyond the door perhaps someone might be moving. It was now, as nearly as Renwick could judge, about one o'clock in the morning. He crossed the crypt carefully and found the partition, feeling its surface, which was made of rough boards loosely nailed together. He put his eye to one of the cracks and peering in, could see nothing; but a current of warmer air which came through the slits, slightly aromatic in odor, warned him that the space beyond was surely connected with the habitable part of the castle--a wine cellar perhaps, or a storage room. He debated for a moment whether it was wise to use another light and then at last decided to take the risk, and as matches were scarce, found the ancient candle in the iron lamp, which after sputtering feebly for a moment, consented to burn. By its aid he examined the dust upon the floor of the crypt, which showed the imprint of no footsteps but his own; then the walls of the crypt, discovering immediately another door which his eyes had missed in the earlier glow of the match,--a narrow door open to the left, of thick wood, with heavy iron hinges, the flanges of which formed the braces of the door itself. He blew out the candle and put it into his pocket. Peering through the keyhole and seeing nothing, he lifted the latch and tried to open it.
His efforts proved that it had been unused for many years, for the hinges had sagged, and some of its weight rested upon the stone floor. But with an effort, he managed to move it an inch or so. Another effort swung it clear of its stone sill, and at last he managed to open it wide enough to admit the passage of his body. But with this last attempt the rusty hinges rasped horribly; and so he waited in silence, listening fearfully for any sounds in front or behind him which might indicate alertness above.
